General Purpose Polystyrene (GPPS3160) is a transparent and rigid grade from the thermoplastics family, produced by polymerizing styrene in petrochemical plants. Due to its high optical clarity, smooth surface, and easy moldability, it is an ideal choice for products where transparency and surface quality are important. The 3160 code typically refers to specific technical properties such as melt flow index (MFI) and molecular weight distribution, which make this grade optimized for processes like injection molding and thermoforming.

Features and Benefits:

• High transparency and surface gloss
• Suitable heat resistance for general applications
• Easy processability and short production cycle
• Compatibility with various pigments and additives

Typical Applications:

Manufacturing of transparent disposable containers, food packaging, lightweight household items, decorative parts, transparent enclosures, and display products where visual clarity is essential.

Thanks to its balance of cost, aesthetics, and processing convenience, GPPS3160 is among the best‑selling grades in the Iranian packaging and household goods industries.
